Efficacy of auricular acupoint bean-embedding therapy in the treatment of residual dizziness after successful reduction of benign paroxysmal positional vertigo and its effect on skin sympathetic response / 中国基层医药

ABSTRACT

Objective:To investigate the efficacy of auricular acupoint bean-embedding therapy in the treatment of residual dizziness after successful reduction of benign paroxysmal positional vertigo (BPPV) and its effect on skin sympathetic response.Methods:A total of 110 patients with residual dizziness after successful reduction of BPPV who were admitted to Wenzhou Hospital of Traditional Chinese Medicine from January 2019 to May 2021 were included in this study. They were randomly divided into control and study groups, with 55 patients in each group. Patients in the control group were treated with drugs, and those in the study group were treated with auricular acupoint bean-embedding therapy. Before and after treatment, dizziness handicap inventory (DHI) score, activities-specific balance confidence (ABC) score, and Hamilton Anxiety Scale (HAMA) score were compared between the two groups. The latency and amplitude of sympathetic skin response (SSR) were measured.Results:After 15 days of treatment, DHI scores of all dimensions in the study group were significantly lower than those in the control group ( t = 16.13-20.62, all P < 0.05). ABC score in the study group was significantly higher than that in the control group [(87.90 ± 6.01) points vs. (80.55 ± 8.73) points, t = 3.10, P < 0.05). HAMA score in the study group was significantly lower than that in the control group [(7.85 ± 1.06) points vs. (13.30 ± 2.49) points, t = 8.43, P < 0.001]. The initial latency value of SSR in the study group was significantly higher than that in the control group [(1.95 ± 0.27) ms vs. (1.67 ± 0.21) ms, and the amplitude of SSR in the study group was significantly lower than that in the control group [(1.49 ± 0.15) mV vs. (1.70 ± 0.22) mV, t = 4.73, 4.04, both P < 0.001]. The incidence of adverse reactions in the study group was significantly lower than that in the control group [0.0% (0/55) vs. 10.9% (6/55), χ2 = 4.40, P < 0.05]. Conclusion:Auricular acupoint bean-embedding therapy can effectively alleviate the symptoms of dizziness after successful reduction of BPPV, improve patient's psychological status and autonomic nerve function, which is worthy of clinical promotion.
